Hemodynamic Effects of Transcatheter Tricuspid Valve Annuloplasty With Cardioband and Their Associations With Clinical Outcomes
Authors' conclusion
Postprocedural XV height was independently associated with 2-year survival and linked to TR reduction and right ventricle remodeling. TTVA improves hemodynamics even in advanced TR, and hemodynamic markers may support risk stratification.
Study context
- Population
- Patients with severe functional tricuspid regurgitation (TR) who underwent transcatheter tricuspid valve annuloplasty (TTVA) with the Cardioband system between 2019 and 2022patients with complete hemodynamic assessment
- Participants
- 58 patients
- Exposure
- Hemodynamics before vs after cinching
- Outcome
- 2-year survival
- Follow-up
- 2 years
Methodological detailsretrospective
- Retrospective
Main finding
As reported in the abstract
- Lower postprocedural XV height independently predicted 2-year survival
- P =0.002
- Immediate right ventricle remodeling associated with 2-year survival
- P =0.024
Observational data: associations, not effects.

- XV height
- 12.5 to 7 mm Hg; P <0.001
- Right atrial pressure (mean/V-wave) decreased significantly
